Fresh hacks every day
The ATtiny series of processors is incredibly popular. We've seen so many different projects utilizing these tiny powerful microprocessors. They're tiny enough to fit on a business card, yet powerful enough to do all kinds of cool things. We've seen them used for video games, fm transmitters, custom USB business cards, Halloween costumes, LED cubes, even dashboard modifications.
Some people get nervous to try them because they require some programming, but you can even program an attiny with an arduino. Moving to the ATtiny is the next logical step after you make a project using an arduino, so give them a try!
[ch00f] is at it again, expanding the horizons of the art of PCB business cards. This one draws his logo on any computer over a USB port.
The physical design of the card is heavily inspired by [Frank Zhao]‘s card; both use an ATtiny85 and the V-USB package to handle the USB protocol and communications. Instead of typing … Read the rest
This project started as a simple microcontroller replacement on this IR camera remote control PCB. But the soldering job went rather badly for [Balthamos] so he changed things up and designed his own simple AVR remote shutter release and intervalometer.
The DIP chip seen with most of its legs bent backwards is the ATtiny25 which makes the system work. … Read the rest
[Michael] built his own LED marquee using individual diodes. Despite his choice to forego the 8×8 or 5×7 modules we often see in these projects, his decision to spin a dedicated PCB saved him a lot of trouble during assembly. Sure, he still had to solder 180 leads on the 9×18 grid of lights, but at least he didn’t … Read the rest
On November 23rd last year, [Dhairya] attended a little shindig at MIT. Three drinks into the night, he blacked out and woke up in the hospital the next day. It was an alcohol-induced blackout, and like all parties at MIT, there’s an ingenious solution to [Dhairya]‘s problem.
[Dhairya] came up with an alcohol-aware ice cube made of a coin … Read the rest
It’s that special time of year again where the smell of baking cookies fill the house and shopping mall parking lots are filled with idiots and very angry people. [Kevin] thought it would be a good idea to build an LED Christmas tree and ended up building a great looking tree that’s also very simple.
In the video, the imgur … Read the rest
We’re very accustomed to seeing small media player builds, but [txyz]‘s ATtiny-powered audio player is one of the smallest and most feature-packed we’ve seen.
The audio player is powered by the very small and very inexpensive ATtiny2313. The music is stored on an SD card – a maximum of 2GB of WAV files recorded in mono at 32kBps at an … Read the rest
In an effort to be more relevant to children that just aren’t impressed with crayons and markers anymore, Crayola released the ColorStudio HD pen. Instead of ink, this pen is filled with electronics that communicate with a tablet to draw different colors in the Crayola ColorStudio app.
[Rob Hemsley] had done some work with capacitive touch screens before, so when … Read the rest
